Chesapeake’s Key Operating Areas

Characteristics of Shale Formations Found in organic-rich sedimentary rocks (shales) that were originally deposited as muds within tidal flats and deep water basins Shale formations can be found 1 mile or more underground Dense rock with low permeability Typically requires a combination of horizontal drilling and hydraulic fracturing for the natural resources to be recovered in economic quantities

The Production Process Five basic steps: 1. Site selection and well pad preparation 2. Drilling the well 3. Completing the well 4. Marketing the resources 5. Reclaiming the site

Site Selection A number of factors are considered in selecting a drilling site: Favorable geology Topography Access Roads Routes for pipelines and utilities Proximity to schools or residential areas Environmental factors such as wetlands and sensitive wildlife habitat Available water source(s)

Well Pad Preparation Well pads can be located in rural or urban areas Pad preparation requires approximately 4-6 weeks Typical horizontal well pad requires 3-5 acres to construct

Advanced Drilling Technologies Reduce Surface Footprint Vertical drilling patterns required: Up to 16 well pads needed to recover the natural resources from 640 acres Multiple roads with pipelines and utilities required to access the wells Total surface disturbance was ~45 acres

Extraordinary Technology Advances Extract Natural Gas More Effectively Horizontal drilling substantially reduces surface footprint 6-8 horizontal wells anticipated drilled from each 3-5 acre pad Only one road with pipeline and utilities to well pad Approximately 85% less surface disturbance than from with vertical wells

Drilling the Well Using Today’s New Technology Wells are drilled and constructed to recover the natural resources while protecting the environment and providing for the safety of workers and area residents Drilling is a 24/7 operation Reduces rig time on location The drilling phase is a temporary operation, typically lasting 3-4 weeks per wellbore Chesapeake Energy utilizes a “closed-loop” drilling system All drilling materials are contained No materials collected in earthen pits

Drilling the Well-Groundwater Protection 4 or more layers of protection are installed in the well to isolate the well from the surrounding strata and protect groundwater supplies and the environment Multiple layers of steel casing and cement are utilized Casing set in place below freshwater aquifer zone

Using Horizontal Wells Computer-driven, state-of-the-art technology allows for horizontal drilling Horizontal drilling allows for access to a greater volume of the shale resource reservoir Access to a greater volume of the reservoir makes shale resource development economical

Well Completion After the drilling rig is removed, hydraulic fracturing (“fracing”) begins Fracing is a process to stimulate natural resource production from the hard shale Impoundments, if necessary, hold freshwater only Water is mixed with proppant (such as sand) and pumped into the shale reservoir under pressure 99.5% of fracturing fluid is made up of water and sand Generally takes several days per wellbore For more information on hydraulic fracturing, please visit AskChesapeake.com

Aqua Renew Program Process Currently recycling/reusing nearly 100% of water used during the production process Benefits Reduces or eliminates need for water to be sent offsite for disposal Reduces required water supplies Reduces truck traffic, lowers impact on roads, noise, and air Reduces the cost of operations For more information on the Aqua Renew program please visit AskChesapeake.com

Marketing /Reclaiming the Site Gas and liquids are separated by the “separator” Pipeline carries natural resources to market Produced water is retained on location in tanks until removed via truck Site is reclaimed and landscaped Site is reduced to approximately 1 acre Small access road will be retained Company returns regularly Maintain equipment/monitor production rate
